Our hands and feet are used most often, and the fingers and toes are very prone to injuries. Our nails, which are composed of hard protein called keratin, serve as protective covering to somehow shield our finger and toe tips.
Being rich in nerve endings, our fingers are highly sensitive areas making them prone to shock and various kinds of injuries like cuts, burns, bruises and trauma. That’s why we need to have complete and healthy nails.
What composes our nails?
In common usage the word NAIL usually refers to the nail plate only, that hard part which is made of a tough protein called cartilage and produced from living skin cells in the fingers and toes. But anatomically, fingernails and toenails are made up of different parts:
The free edge, that which grows past the finger beyond the nail plate
Cuticle (eponychium), the fold of skin at the nail’s proximal end
Paronychium, the fold of skin on the sides of the nail
Hyponychium, the attachment between the skin of the finger or toe and the distal end of the nail
Nail plate, the hard and translucent portion, composed of keratin
Nail bed, the adherent connective tissue which underlies the nail
Lunula, the crescent-shaped whitish part of the nail bed when it is visible
Nail fold, a fold of hard skin overlapping the base and sides of a finger nail or toe nail
